Abstract
Abstract A combination electronic digital wristwatch and electronic shift scheduler using a digital liquid crystal display, enclosed within a watch-type case, for use primarily by firefighters. The invention provides both a device and a method that allows an individual who needs to keep track of platoon and shift schedule information to enter, display, review, search, and modify that information on a full-function wristwatch. The combination includes time and date display, a chronograph function, and an alarm clock with chime. Four switches are connected to a signal conditioner for encoding each switch closure to be input into a CPU which generates the required signals for the display after reference to the calendar information stored in the ROM and the user input information stored in the RAM. The CPU makes the calculations required for the operation of this invention. It also calculates the repeating cycle of the schedule and applies it to the calendar information both prospective and retrospective to determine the platoon assignment for each time interval and its start time. It is preferred that the timepiece be at least water resistant, particularly for its intended application in the firefighting profession.
